Abstract
A drive roller, driven by a motor, moves a material web on a set of rollers. The present rotational speed of the motor is detected. A current web speed is determined from the detected rotational speed and a diameter of the drive roller. The current web speed is compared with a specified target speed value and a specified threshold speed value of the web speed.
